TEMPORARY BINDER.

Specification of Letters Patent.

Patented Mar. 17,1914.

To all whom it may concern Be it known that I Gnonon I. WVIGGINToN, a citizen of the United States, residing at Kalamazoo, Michi an, have invented certain new and usefiil Improvements in Temporary Binders, of which the following is a specification.

This invention relates to improvements in temporary binders.

My present improvements are particularly designed by me for embodiment in a binder of the type shown in Letters Patent #1,010,556, issued to me December 5, 1911, and are an adaptation and in some respects, an improvement upon the structure there illustrated.

The main objects of this invention arei First, to provide in a temporary binder or loose-sheet holder, an improved adjusting mechanism. Second, to provide an improved temporary binder or loose-sheet holder which is capable of very rapid manipulation to permit the removal or insertion of leaves, and one in which the sheets may be very securely clamped, the mechanism simple and compact.

Further objects, and objects. relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanging drawin forming a part of this speci cation, in w ich:

Figure I is a detail inside plan view of a structure embodying my invention with the covers extended, the leaves being shown in an n right position. Fig. II is an enlarged detai section on a line corresponding to line 2-2 of Fig. I. Fi III is an inverted detail view of the bin er ad'usting mechanism. Fi IV is an enlar e detail section through t e adjusting mec anism, on a line correspondin to the broken line 4-4 of Fig. III. Fig. V is "a detail view of the ad usting pinion and its support, a portion of the support bein broken away to show the arrangement of die pinion therein. Fig. VI is a view showing connections for the back strip 6 to the adjusting member 7. Fig. VII is a detail inside plan view of a modified structure, the binder being shown open and the leaves in an upright position. Fig. VIII is a detail section .on a line corresponding to line 7-7 of Fig. VII. Fig. IX is an inverted detail of the rack bar and the adjusting slide 27 of the modification of Fi VII.

Re .erring to the drawing, the covers 1 and 2 in the embodiment of my invention illustrated, are substantially the some in structure as that of my patent hereinbefore referred to. The clamping bars 3 are pivotally connected to the covers as by the hinges 3'. The binding cords or members 4.- are secured to the cover 1 and adjustably connected to the cover 2. The cover 2 is provided with a recess 5 for the adjusting mechanism and with a chamber 5' at the rear of the recess for the back strip 6. The adjusting member 7 for the binding members 4 is slidably mounted on a rack 8 arranged longitudinally of the cover recess. The adjusting member 7 is preferably formed of sheet metalwith loops 9 struck down therefrom to slidably engage the rack bar 8. See Figs. I, II and III.- A pawl 10 is pivoted on the adjusting member 7 at 11 to coact with one edge of the rack bar, the rack bar being, in the structure illustrated, provided with teeth on each edge. The adjusting member is provided with a segmental slot 12 through which the finger piece 13 of the pawl is arranged. The pawl is held yielding y in its engaging and disengaging positions by means of the U-shaped spring 14, one arm of which is mounted on the pivot 15 and the other engages the pawl. See Fig. III. The spring 14 is thus adapted to hold the pawl in either its engaging or disengaging positions. substantially as in the structure of my said patent.

To tighten the binding strips or apply clam ing stress thereto, I provide a pinion 16 w ichis arranged in a cup-like seat 17 in the support 18. This support is a sheet metal stamping, the seat being struck therefrom and being cylindrical so that the pinion is a turning fit therein. Thus arranged no journals for the pinion are required. The seat is cutaway on one side so that the pinion is supported in mesh with the rack bar, as shown in Fig. III. The inion is provided with a squared hole 19 a apted to receive the tan 20 of the key-like spindle 21. The adj ing member 7 and the pinion member support; 18 are provided with holes 22 adapted to receive the spindle and constituting bearings therefor. By thus arrangii'lg the parts, the adjusting member is actuated to tighten the binding strips or lllGllll )Cl' by means of the key or spindle 21 and is held in its adjusted position by means of the pawl. 'hen it is desired to release the member, the pawl is shifted to inoperative position when the adjusting member moves freely on the bar 8. The back strip. (3 is connected to the adjusting member 7, by the spring 33 one end of the spring being secured to the stud 28 extended through the slot. 24 in the wall 25. The spring is preferably S-shaped, its other end being connected to the back strip by a suitable clip 34.

In the modification shown in Fig. VI, the adjusting pinion 26 is mounted on the slide 27, the slide being provided with a suitable housing 28 constituting with the slide, bearings for the spindle 29 of the pinion. The spindle 29 is provided with a collar 30 on which the finger piece 31 is pivotally mounted. The slide is provided with diagonally opposed rack engaging lugs 32 which slidably retain the same upon the bar to permit its being engaged and disengaged as desired, the object of this being to permit the use of these adjusting slides on binders such as are shown in my said patent or in the modification shown herein, in which no pinion is provided on the adjusting member. The operation of this modified structure is substantially the same as that of the preferred construction.

My improved binder is very simple and economical in structure and is easily and quickly adjust-ed. I have illustrated and described my improvements in the form in which I have embodied them.

While I am aware that various modifications in structural details are possible, I have" not attempted to illustrate or describe the same herein as I believe they will be readily understood by those skilled in the art to which this invention relates from the disclosures herein made.

Having thus described my invention, what I claim is new and desire to secure by Letters Patent is 1.
